As of 2026-09-11 · the last 10 years
Hassium’s research intensity has fallen to about 9% of its all-time peak, a steady decline from a high point reached in 2009, which lies before this window.
Research intensity ran from about 20% of the element's own all-time peak in 2016 to about 9% in 2026 — a steady decline, and the all-time peak (2009) lies before this window. Over the same span its share of research attention across all elements fell. Among the 118 elements, hassium has one of the smaller research literatures of any element.
The number of papers involving the element rose from about 15 in 2016 to about 22 in 2025 (1.47x). That is slower than the literature as a whole grew over the same years, so the element lost ground in the wider body of research even as its own count rose.
The primary research community is Synthesis and Decay of Superheavy Elements and Heavy-Ion Collision Physics. Hassium is a minor presence in this much larger community, with under 1% of its papers involving hassium. However, this group accounts for 100% of hassium’s recent research, a share that has risen from 75% in the previous period. A key paper in this area, "Validating Vacuum Chromatography with Subsecond Radioisotopes of Hg for Superheavy Element Chemistry" (2026), is cited once. Another significant work, "Vacuum Chromatography of Tl on SiO 2 at the Single-Atom Level" (2016), is cited about 33 times.
Two other communities, Silicon-Germanium Quantum Devices and Laser-Structured Surfaces and Actinide Chemistry and Nuclear Fuel Materials, have seen their share of hassium research decline to zero. In the former, hassium is also a minor presence, with under 1% of papers involving the element. A paper in this group, "Lorenz gauge, electric and magnetic fields study of interaction of gravitationally accelerating ions through the super contorted 'tubular' polar areas of magnetic fields and hassium nanoparticles" (2020), is cited about 30 times. The Actinide Chemistry community also shows a declining trend, with no recent hassium-specific papers identified in the current window.
